902. WINDSTORM MITIGATION FEATURES

A. For policies that cover the peril of Windstorm or Hail, a premium credit may be available if one or more of the following loss mitigation features or construction techniques exists: a. Roof Covering; b. Roof Deck Attachment; c. Roof-Wall Connection; d. Opening Protection; e. Roof Shape; or f. Secondary Water Resistance The credit recognition and description of the loss mitigation features listed above are outlined in the Loss Mitigation Credits Table contained in Paragraph F. below. (Note: n/a to mobile home policies.)

B. Proof of Compliance

Citizens requires proof to substantiate the existence of loss mitigation features displayed in the Loss Mitigation Credit tables, except roof shape that is verifiable via a photograph.

Citizens ePAS system will default loss mitigation features displayed in the Loss Mitigation Credit tables to values that return the least amount of credit. Proof to substantiate the existence of loss mitigation features will be required when values other than the defaults are selected, except roof shape that is verifyable via a photograph.

Mitigation affidavits/forms are available on Citizens website to verify mitigation features and obtain additional premium credits.

The insured is responsible for the expense associated with the use of these forms or any other costs for substantiating the existence of the mitigation features.

Exceptions to use of forms listed above:

? Year built on or after January 1, 2002:

Structures built on or after January 1, 2002, are

eligible for the minimum FBC 2001 credit by

providing documentation that validates the year of

construction. Acceptable documents include:

certification of occupancy, copy of property

appraisal or any other document Citizens deems

acceptable.

Completion of mitigation

affidavits/forms are not required to receive the

minimum FBC 2001 credit. Additional credits

may be obtained by completing mitigation

verification affidavits/forms available on our

website.
